Maxim Integrated MAX6412UK22+T Microprocessor Reset Circuit

The MAX6412UK22+T is a high-quality microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a renowned leader in analog and mixed-signal products. This compact and efficient component provides a crucial function in digital systems: it monitors the supply voltage to ensure that it remains within acceptable limits, thereby safeguarding the system against improper operation during power-up, power-down, and brown-out conditions.

Encased in a space-saving 5-pin SOT-23 package, the MAX6412UK22+T is particularly suitable for portable and space-constrained applications. It operates over a wide voltage range and features a factory-set reset threshold voltage of 2.20V, which is ideal for systems that run on 2.5V power supplies. The reset output remains asserted for a minimum of 140ms after the supply voltage exceeds the reset threshold, providing ample time for the µP and other system components to stabilize.

One of the key attributes of the MAX6412UK22+T is its low power consumption. With a quiescent current of just 1.2µA, it is an excellent choice for battery-powered devices where power efficiency is paramount. This low power draw helps in extending the battery life of the application it is used in.

Moreover, the device features a debounced manual reset input, which allows for a forced reset of the connected microprocessor. This is a valuable feature for system maintenance or when a manual system restart is required. The manual reset function is also an important feature for enhancing the reliability and safety of the overall system.

The MAX6412UK22+T is designed to be robust and reliable, with built-in immunity to short-duration transients on the VCC line. This makes it an excellent choice for industrial, automotive, and other environments where electrical noise and transient conditions are common.

In summary, the Maxim Integrated MAX6412UK22+T offers a combination of features that make it an essential component for any system requiring reliable voltage monitoring and reset capabilities. Its compact size, low power consumption, and robust design make it a versatile solution for a wide range of applications.
